Hi, Paolo Bonzini from qemu team has finally applied my qemu jemalloc patch in his for-upstream branch https://github.com/bonzini/qemu/releases/tag/for-upstream https://github.com/bonzini/qemu/tree/for-upstream So,It'll be in qemu master soon and ready for qemu 2.5 I have write some small benchmark results with librbd in the commit itself https://github.com/bonzini/qemu/commit/efc1e9f08020cd460eb2204e3092b39e408e1fa9 you simply need to compile qemu with --enable-jemalloc, to enable jemmaloc support.
